Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a simple hook for overhead cable laying. Background Technology

[0002] In the construction of bridges, buildings and other projects, laying construction cables haphazardly on the ground seriously threatens the safety of construction workers and slows down the construction progress. Therefore, overhead cable laying has become a necessary measure.

[0003] A search revealed Chinese patent CN212435311U, which discloses a simple, safe, and quick anti-detachment hook for cable stringing. This invention relates to a cable hook that solves the problem of inconvenience in attaching hooks to steel strands in existing technologies. The hook unit includes a support rod and two connecting rods, with the two connecting rods fixedly connected to both ends of the support rod. Each hook unit has a hanging ring, and the ends of the two connecting rods furthest from the support rod are fixedly connected to the hanging ring. It also includes a pull rope. Several hook units are provided, and each hook unit is fixedly connected to the pull rope along its length. This invention provides a certain degree of convenience in suspending the cable on steel strands.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The cable overhead laying method described in the aforementioned patent uses steel strand installation, which involves complex hook installation and is susceptible to loosening due to environmental factors. The cable trays are also costly and heavy, resulting in slow installation and reduced construction efficiency. Furthermore, the installation and maintenance are inconvenient, which makes it impossible to guarantee the safety of construction. Therefore, the patent has certain limitations.

[0008] A pin, which is fixedly mounted on a steel hook;

[0009] The anti-disengagement locking assembly includes an anti-disengagement hook rotating rod that is rotatably mounted on a steel hook via a pin.

[0010] Preferably, a hook handle is fixedly installed at one end of the steel hook, a lock seat is fixedly installed on one side of the hook tip, a lock groove is opened on the other side of the hook tip, and one end of the anti-disengagement rotating rod is set inside the lock groove.

[0011] Preferably, a wedge-shaped latch is fixedly installed on one side of the lock seat, a lock body switch is fixedly installed on the surface of the lock seat, and a switch groove is provided on the lock seat.

[0012] Preferably, a spring seat is fixedly installed on one side of the wedge-shaped locking tongue, and a spring is fixedly installed between the spring seat and the lock seat.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model can simplify the construction process, reduce installation difficulty and cost, improve construction efficiency, and enhance the safety of overhead cable laying. It has important practical significance for ensuring the safety of bridge and building construction, reducing costs, and promoting the smooth progress of projects.

[0015] Secondly, this utility model adopts a double-hook suspension method for overhead cable laying, and both hooks are equipped with anti-detachment devices, which are safe and reliable. In addition, by setting a freely controllable locking tongue switch, it can be installed and disassembled with one click, which greatly improves the efficiency of cable laying. Furthermore, the materials used in this device are readily available and can be recycled, which is in line with the concept of green construction.

[0016] This solution addresses the problems of existing overhead cable laying methods that use steel strands, which involve complex hook installations that are susceptible to loosening due to environmental factors, high cable tray costs, heavy weight, slow installation, reduced construction efficiency, and inconvenient installation and maintenance, ultimately compromising construction safety.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides a simple hook for overhead cable laying through improvements. The technical solution of this utility model is as follows:

[0028] like Figures 1-6 As shown, a simple hook for overhead cable laying includes a steel hook 1 and a hook tip 9. The hook tip 9 is fixedly installed at the other end of the steel hook 1. This hook device can quickly realize cable overhead laying, improve construction efficiency, and has strong safety performance. It also includes an anti-derailment locking assembly.

[0029] Pin 6 is fixedly installed on steel hook 1, which facilitates the flexible rotation of the hanging rod;

[0030] The anti-detachment locking assembly includes an anti-detachment hook rod 4 that is rotatably mounted on a steel hook 1 via a pin 6, preventing the cable from falling off and greatly improving the efficiency of cable laying.

[0031] Furthermore, a hook handle 5 is fixedly installed at one end of the steel hook 1, a lock seat 3 is fixedly installed on one side of the hook tip 9, and a lock groove 7 is opened on the other side of the hook tip 9. One end of the anti-detachment hook rotating rod 4 is set inside the lock groove 7, and an anti-detachment and suspension device is provided, which is safe and reliable.

[0032] As a further embodiment of this utility model, a wedge-shaped locking tongue 8 is fixedly installed on one side of the lock seat 3, and a lock body switch 2 is fixedly installed on the surface of the lock seat 3. A switch slide groove 12 is provided on the lock seat 3. The cable can be quickly laid overhead through the lock body switch 2. It can also be quickly disassembled when the construction is completed, with basically no damage to the structure. It can be stored with one click, reused, and without wasting materials.

[0033] Furthermore, a spring seat 11 is fixedly installed on one side of the wedge-shaped locking tongue 8, and a spring 10 is fixedly installed between the spring seat 11 and the locking seat 3 to increase the rebound force of the locking tongue and ensure a tight and secure engagement.

[0034] The specific working method is as follows: First, design the cable laying route and the installation location, quantity, and size of the steel hooks 1. Check the stability of the overhead structure. Check if the anti-detachment lock can be used normally (locked and open states). If there is no overhead structure, an overhead suspension cable can be erected, and the steel hooks 1 can be hung on the suspension cable to complete the overhead laying. Open the hook, insert the cable, and rotate the anti-detachment rod 4. Rotate the anti-detachment rod 4 and press it into the lock groove 7 until a locking sound is heard. Hang the other hook on the overhead structure, similarly rotate the anti-detachment rod 4 and press it into the lock groove 7, and pull it to check for tightness. When disassembling, slide the lock body switch 2 to the open state, turn out the anti-detachment rod 4, and remove the hook. Remove the cable from the other hook in the same way. It is strictly forbidden to hang the cable on unstable overhead structures. Do not hang too many cables at once. If multiple cables need to be laid, multiple steel hooks 1 can be installed.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
